Generic and bland-- and I'm being kind.
But, from a marketing angle, this makes sense. J. Crew already has a solid and established customer-base, and to many others, it's a "designer" brand worthy of prestige, so slapping some young, hip designer's name onto another commercial line of theirs just makes that line more attractive to some people-- for no other reason then that it has some designer's name on it, even if it's identical to anything else from J. Crew. The power of branding.
